As an operator-planner in an Independent System Operator, you create a base case for tomorrow's peak hour each morning in order to establish the voltage profile and verify that the day-ahead market schedule is AC-feasible. In order to do this, you should use the model described in `math-model.md` to find a least-cost, AC feasible operating point and then produce a report in `report.json`. The report should follow the structure below with all power values in MW or MVAr, angles in degrees, voltages in per-unit.
